ABS-ESD AS-PERM
Additive grade

What is ABS-ESD AS-PERM?
ABS-ESD AS-PERM is ABS-ESD in the AS-PERM grade — pick when colour other than black is required and only antistatic (10¹⁰–10¹² Ω, no charge build-up) rather than full ESD dissipation is specified. ABS-ESD AS-PERM has a yield strength of 38 MPa (5.51 ksi) and a tensile strength of 40 MPa (5.8 ksi) — weaker than 64% of polymer grades. Elongation at break is 15% and the elastic modulus is 2.3 GPa (0.334 Msi). ABS-ESD AS-PERM has a density of 1.04 g/cm³ (0.0376 lb/in³), lighter than 71% of polymer grades. Its glass-transition temperature is 108°C (226 °F).

Working with ABS-ESD AS-PERM
Is ABS-ESD easy to machine?
Machines easily with sharp single-flute or O-flute cutters at high rpm/low feed; keep chips clear and avoid coolants containing ketones, and note that heavy sanding can locally alter surface resistivity.
Can ABS-ESD be welded?
Joins well by solvent bonding (avoid on ESD-critical surfaces), ultrasonic and hot-plate welding; conductive-filled joints may need a bridging conductive adhesive to keep the path continuous.
Can ABS-ESD be formed, bent or molded?
Dry 2–4 h at 80 °C before printing/moulding; FDM needs a 90–100 °C heated chamber and 230–265 °C nozzle to limit warping, injection at 220–250 °C melt / 50–80 °C mould with moderate shear to preserve the carbon network.
What surface finishes work on ABS-ESD?
Supplied black only; vapour smoothing or paint/primer will insulate the surface and destroy ESD function, so leave working faces as-printed or lightly bead blasted and verify surface resistance per ANSI/ESD STM11.11.
ABS-ESD chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
